OAKLAND — A high-speed round-trip car chase from Oakland to Treasure Island ended Tuesday morning with the arrest of two men and a woman suspected in a series of Oakland street robberies, police said.

Police said the suspects, two men ages 22 and 21 and a 20-year-old woman whose names were not immediately released, are responsible for at least four robberies between Monday night and Tuesday morning, and possibly more.

Some of the robberies involved a gun, but no weapon was immediately recovered and investigators continued interviewing the suspects Tuesday night, police said.

Harry Harris is a Pulitzer Prize winning breaking news reporter for the Bay Area News Group. He began his Oakland Tribune career in September 1965 as a 17-year-old copyboy. He became a reporter in 1972 and is considered one of the best crime and breaking news reporters in the country. He has covered tens of thousands of murders and other crimes in the East Bay. He has also mentored dozens of young reporters, some of whom continue to work in journalism today.

"There is a general recognition that we don't need these military-style weapons in New Zealand, so it's very easy to win cross-party support for this," said Mark Mitchell, who was defense minister in the previous, center-right government and who supports the ban initiated by the center-left-led Labour Party.
